Abstract

The invention relates to a hydrofoil catamaran hardware-in-the-loop simulation system which comprises a hydrofoil system, a six-degrees-of-freedom stabilized platform, an attitude and heading reference system, a hydrofoil catamaran motion data acquisition unit, a hydrofoil catamaran interference simulation unit, a hydrofoil catamaran motion information simulation unit, a hydrofoil catamaran motion control unit, and a hydrofoil catamaran motion demonstration system. The hydrofoil catamaran interference simulation unit simulates external interference information, the hydrofoil catamaran motion data acquisition unit acquires the motion information of a catamaran body, and the hydrofoil catamaran interference simulation unit and the hydrofoil catamaran motion data acquisition unit send the external interference information and the motion information to the hydrofoil catamaran motion control unit, so that simulation of the multiple-degrees-of-freedom motion status of a hydrofoil catamaran in a complicated water surface environment is realized. Based on the hydrofoil catamaran hardware-in-the-loop simulation system of the invention, the dynamic characteristics of a hydrofoil catamaran can be reflected more comprehensively and more truly, and the multiple-degrees-of-freedom motion status of a hydrofoil catamaran in a complicated water surface environment can be simulated.

Description

technical field [0001] The invention relates to a half-physical simulation system of a ship, in particular to a half-physical simulation system of a hydrofoil catamaran. Background technique [0002] At present, a hydrofoil catamaran is a composite high-performance ship of a new concept that combines the advantages of a high-speed catamaran and a hydrofoil. It has two hulls, and the hulls are connected by decks and hydrofoils. Due to the unique hydrofoil and catamaran structure of the hydrofoil catamaran, the hydrofoil catamaran does not have self-stability in the wing navigation state, so it is necessary to design a special hydrofoil control system to maintain the hydrofoil catamaran wing navigation. Sailing stability and resistance to changes in the state. In the actual development process of the hydrofoil catamaran control system, it is necessary not only to study the specific control algorithm but also to collect the actual data of the hydrofoil catamaran sailing in var...
